Application led January Ei, 191'?. Serial No. 141,392.

' To dit' 'whom t may concern.:

rThis invention relates to `rubber Workingv apparatus and consists in certain improvements in the construction'thereo as Will be hereinafter fully described and pointed out in the claims.

The object of the invention is to reduce end einiplify the labor involved in making cesttiin rubber articles, particularly inner tubes tor tires'.

rl`he invention is illustrated in the accompanying ldrawings as follows :e-

liigure 1 is an end View of the apparatus..

l'n the making oli tubes the rubber sheet is out to length, rolled on a. pole and the rubbor ointhqpole thenvvrapped With a fabric so as to hold the rubber sheet iwhile it is being vulcanized. Ordinarily the operation lirst involves the cleaning oft the pole so as to obiiate the markiingorv sticking of the rubber to it as it is vulcanized. ln 'this apparatus, 1 marks the pole cleaning machine, 2 the cutting bench, EES the tube rollin bench and s the pole Wrapping machine. fore 'the practice has been to separate these did-'arent devices and do the did'erent operations in considerable quantities at points not innncdiately 'adjacent 'lhe details ofihe pole cleaning machine Aforni no part of this invention. 1t comprises the head-piece 5 carried in the loearirnlggs 6. The hcad-piece is driven from a pulley 7 through a friction clutch 8. rli`he friction clutch is normally held out of engagement by a spring 9 and is drawn into engagement bv the cables 10 operating` from a `vfoot lever 11. A tail-piece 12 is carried by bearings 13 and iorced forward by a spring 14. A pole 15 is engaged by the head-piece 5 und centered and held against theheadpiece by the taihpiece through the action of the spring 14. lt is rotated rapidiy and thoroughly cleaned.v lt will be understood that even finger marks on the pole will show on the finished tube so that the pole must be carefully cleaned and handled with 'this in view.

I rear sides of the benches.

After the pole is cleaned it should be carried to a point of easy access to the operators on the rolling bench 3. I accomplish 'this in a simple and convenient manner by providing the ways 16 which are formed of pipe and extend across the benches 2 and 3 at a height just suliicient to clear the heads of the operators. These Ways lare supported by the uprights 17 and 18 arranged at the The Ways are slightly inclined and provided with stops.

19 which are locked with set screws 20 and may be adjusted along the Ways* as desired. The poles as they are cleaned are placed by the opera-tor of the cleaning machine on the ends of the Ways. The pole then rolls down the Way by gravity, the engagement of the ple with the two ways keeping it in para e.

A. sheet supply roll 21 is carried by the brackets 22 extending from the end of the cutting bench 2. The cutting surface 23 on Vthe cutting bench, ordinarily formed ot zinc -or similar material is at a proper height to receive the sheet from the roll 21. Scales 24E and 25 are arranged at the rear side of the bench 2 These scales are arranged in reverse relation, preferably 'With thc zero points toward each other. As indicated the scale 24 has marks one inch apart starting With one and ending with twelve, While the scale 2l has the marks seventy-two 'and cxtending up as far as desired. Two operators usually Work in this cutting and rolling. rlhe sheet is pulled forward rapidly to some point opposite the scale 24. The operator at this end calls the point to the operator opposite the scale 25 and the operator at the scale 25 makes the proper deductionfrom the desired length as indicated on the 'scale 25-and makes the cut. Thus if a, sheet eighty inches is desired and the end opposite the clear and then bringing itdown betweenvthe ways. The tube is rolled in the usual manner on the bench 3 and the tube so rolled is either passed directly to the operator on 5 rollingbench and to the operator handling the wrapping machine.

The wrapping machine has the head 27 mounted in bearings 28. It is driven from a pulley 29 through a friction clutch 30.

1o The friction clutch 30 is normally kept out of engagement by a spring 31 and is thrown into engagement by cables 32 (see dotted lines) operated by a foot treadle 33. A

tail-piece 3l is carried by the bearings 35 and is forced forward by a spring 36. A

bar 37 over which the muslin may be drawn isv also usually supplied. The wrapping machine operates in the usual manner. The pole with the rubber sheet formed thereon is engaged by the head and held in place by the tail-piece. `It is rapidly rotated as the clutch is set and the muslin is wound spirally around the tube, the operator putting the muslin under tension as it is Wrapped. v

The apparatus here described occupies very much less space than is usually taken up by an apparatus accomplishing the same purpose. There is no eXtra handling of so the poles or the parts and very little chance for they accumulation of dirt on the poles or injury to the tube formed on the poles before Wrapping. A very considerable saving of time over usual methods is accom- 9,5v plished.

i What I claim as new is 1. In a rubber-Working apparatus, the combination of a cutting bench and a rolling'bench with intervening spaces for oper- 40 ators; and pole-supporting ways above said benches at a height to clear the heads of the operators.

2. In a rubber-working apparatus, the combination of a pole-cleaning device; a

tube-forming bench in parallel with the pole-cleaning device; and pole-supporting ways above said device and bench at a height to clear the head of an operator and extending to a position within reach of the operator of the pole-cleaning device.

3. In a. rubber-working apparatus, the combination of a polecleaning device; a tube-forming bench adjacent to and parallel to the pole-cleaning device; a tube-wrapping machine parallel and adjacent'. to the tubeforming bench and' at the opposite side of said bench from the pole-cleaningr device; and pole-supporting ways above said device and bench at a height to clear the head of an operator and extending to position to be reached by the operator of the pole-cleaning device.

et. In a rubber-working apparatus, the combination of a polecleaning machine; a sheet-cutting bench adjacent and parallel to the pole-cleaning machine; a tube-rolling bench parallel to the sheet-cutting bench, said benches having intervening spaces between them or operators; a tube-wrapping machine adjacent to and parallel tothe tube1olling bench; and pole-supporting ways above said benches at a height to clear the heads of the operators and extending to a position to be reached by the operator of the pole-cleaning machine.

5. In a rubber-working apparatus, the combination ot' a pole-cleaning machine; a sheet-cutting bench adjacent and parallel to thepole-cleaning machine; a tube-rolling bench parallel to the sheet-cutting ben'ch, said benches having intervening spaces between them or operators; a tube-wrapping machine adjacent to and parallel to the tube--v rolling bench; and pole-supporting ways above said benches at a height to clear the heads of the operators and extending to a position to be reached by the operator of the pole-cleaning machine, said ways being inl clined to permit of the movement of the poles by rolling under the influence oi gravity.

In testimony whereof I have hereunto set my hand.
